Definitions
- the invention relates to a device for cleaning a surface immersed in a liquid, such as that formed by the walls of a swimming pool, in particular of the self-propelled type with electric motor (s).
- Devices of this type very numerous and known for a long time (typically FR 2 567 552, FR 2 584 442 ...), generally comprise a hollow body; one (or more) electric drive motor (s) coupled to one or more motor guiding and driving member (s) of said body on the immersed surface; and an electric pump motor driving a pumping member such as a propeller generating a flow of liquid between at least one liquid inlet and at least one liquid outlet and through a filtration chamber.
- a pumping member such as a propeller generating a flow of liquid between at least one liquid inlet and at least one liquid outlet and through a filtration chamber.
- the pumping is provided by an onboard electric motor, and the drive is also provided by at least one onboard electric motor
- the apparatus if the apparatus must be bidirectional, that is to say be able to perform trajectories forwards and backwards, it is generally excluded to use the electric pumping motor to drive the apparatus in motion, except to provide a pumping member such as a "vortex” or centrifugal pump (cf. for example US Pat. No. 5,245,723), or articulated pallets (see, for example, EP 1 070 850), capable of providing a flow of liquid in the same direction whatever its direction of rotation, but whose pumping performance is poor.
- a pumping member such as a "vortex" or centrifugal pump (cf. for example US Pat. No. 5,245,723), or articulated pallets (see, for example, EP 1 070 850), capable of providing a flow of liquid in the same direction whatever its direction of rotation, but whose pumping performance is poor.
- the trajectories of the apparatus are limited to two predetermined trajectories, one forwards, the other for the rear, that is to say in practice for straight trajectories or trajectories. gyration on one side only. This results in poor sweeping coverage of the immersed surface which is either not completely cleaned or is completely cleaned after a too long period of time.
- EP 1 022 411 discloses an apparatus capable of being partially driven by the hydraulic flow created, and has two nozzle outlets of opposite directions fed alternately by a valve operated when the pump is stopped. With self-rotating wheels or pivoting axles, the forward and backward paths are different. Devices of this type are, however, relatively complex, expensive, and unreliable, particularly with regard to the control valve tilting (or more generally for the change of direction of the hydraulic flow) which requires a logic of operation and at least one embedded actuator and / or a specific mechanism likely to lock up. In addition, again, only two different predetermined paths are possible.
- US 2008/0236628 also describes a submerged surface cleaner device to prevent blocking the device on obstacles on the surface and optimize cleaning.
- This unit generates cleaning jets under the base of the machine body to agitate and lift dirt and debris.
- a pair of nozzles delivering jets of cleaning water are thus provided at the front and rear ends of the body.
- the jet of pressurized water delivered from the front nozzle can be used to help lift the front end of the apparatus to allow it to pass from the wall foot to a vertical surface.
- This water jet at the front end of the device is not likely to cause a single rotation of the device.
- this front water jet does not allow the unit to escape obstacles from the surface immersed or evolve according to different trajectories on the horizontal or vertical walls.
- FR 2925558 discloses an apparatus in which the longitudinal component of the normal hydraulic reaction force is used for the passage at the foot of the wall; FR 2925552 also describes an apparatus in which this same longitudinal component is used for the crossing of steps.
- the object of the invention is therefore generally to propose a cleaning device - in particular of the type with onboard electric motor (s) - which, simultaneously, is more economical in terms of manufacture and use, and presents high performance, comparable to that of known devices, in terms of quality and cleaning, and more particularly providing a complete and rapid scanning of the immersed surface, and good suction quality for the collection of waste with satisfactory energy efficiency.

- the axial pumping propeller 10 In this second direction of rotation, the axial pumping propeller 10 is driven in the opposite direction to its normal pumping direction and generates a non-zero flow of liquid in the retrograde direction, said pitching flow, from the main outlet 37 to the inside the hollow body 1, this rotation rate being evacuated out of the hollow body via at least one secondary outlet 50 opening to the front of the hull, and oriented towards the front so that the liquid flow, called the current of pitching , which escapes through this secondary outlet 50 generates a hydraulic reaction having a component of lifting of the hollow body 1 about the axis 13 of the axle 7.
- two secondary outlets 50 are provided, oriented globally to the front and orthogonal to the axis 13 of the axle 7, symmetrical to each other with respect to a median direction of the axle
- the propeller 10 is an axial pumping propeller with unidirectional and preferably fixed pitch (having blades fixed rigidly on a rotor, extending radially relative to the latter by having a pitch in one direction) generating a flow of liquid oriented generally along its axis of rotation (the helix 10 is not centrifugal type) in one direction or the other in the direction of rotation of the helix about its axis.
- the propeller 10 is optimized to generate an optimal flow when it is rotated about its axis in the normal direction of pumping. But when it is rotated about its axis in direction contrary to this normal direction of pumping, the propeller 10 generates a non-zero flow of liquid in the retrograde direction.
- the pumping propeller 10 is a directly coupled unidirectional pitch propeller rotatably connected to the upper rear end 23 of the drive shaft 9.
- An unidirectional pitch axial pumping propeller comprises blades extending generally radially and having a pitch which is preferably fixed, which could however be variable, but which, in any event, does not change direction, that is to say is always oriented in a single direction direction, so that the direction of the liquid flow generated by the rotation of the helix depends on the direction of rotation of the latter.
- the axial pumping propeller 10 driven in the retrograde direction generates a flow of liquid that can escape from the hollow body 1 by each secondary outlet 50.
- two secondary outlets 50 of liquid are provided, one on each side vertical longitudinal plane of the device.
- Each secondary outlet 50 is provided with a flap 51 mounted freely pivoting about a transverse axis 52 and biased in the closed position, when the motor 8 is driven in the normal direction of rotation, by the effect of gravity and / or by the suction generated by the flow of liquid leaving the main outlet 37.
- the flow of liquid escaping through at least one such secondary outlet 50 is oriented such that this current creates, by reaction, forces whose resultant, called secondary hydraulic reaction force, generates a pitching torque and causes a pitching of the apparatus by pivoting the hollow body around the axle 7.
- This pitching torque around the axis 13 of the axle 7 engine makes it possible to pitch up the apparatus, that is to say to lift the wheel 6 while the device is in displacement on the same wall of the immersed surface.
- a secondary hydraulic reaction force exerts a pivoting torque of the apparatus around the axis 13 of the motor axle 7 in the direction of increasing the pitching device.
- the direction of the flow of liquid generated in the retrograde direction and outgoing by such a secondary outlet 50 is not secant with the axis 13 of the axle 7 engine, and is oriented in the right meaning.
- a hydraulic reaction that can cause, at least from a certain speed of rotation, a pitching of the apparatus causing changes in the trajectory of the device during its movements in the direction back, turning on one side or the other,
- the flap 31 in the upper part of the inlet duct 28 is automatically in the closed position (due to gravity and / or under the effect of the flow in retrograde direction), preventing any backflow debris in the conduit 28, so that the debris remains confined within the filter 33.
- the flow in the retrograde direction is discharged by the secondary outlets 50 whose valves 51 are open by pivoting about their axes 52 under the effect of hydraulic fluid pressure in retrograde direction.
- the flow of liquid escaping from the secondary outlets 50 in the retrograde direction and in the pitched attitude of the apparatus generates a secondary hydraulic reaction force also having at least one component parallel to the rolling plane. capable of causing the movement of the apparatus in the rearward direction of movement.
- the changes in the trajectory of the aircraft during its movements in the backward direction can be obtained in any appropriate way, in particular from the modification of pitched attitude of the hollow body 1 relative to the axle 7 about the axis 13 (in a plane orthogonal to the immersed surface and containing the direction of displacement) from a certain speed of rotation of the engine 8 in retrograde sense.
- the apparatus is designed so that it can be swirled on one side (for example to the left with respect to its direction of movement) for a first speed of the motor 8 corresponding to a first speed -VI displacement of the apparatus in the rearward direction and at a first attitude, for example not pitched, of the apparatus, and in gyration on the other side (for example towards the right with respect to its direction of movement) for a second speed of the motor 8 corresponding to a second speed -V2 movement of the device in the rear direction and a second attitude, pitched, of the device.
- first speed of the motor 8 corresponding to a first speed -VI displacement of the apparatus in the rearward direction and at a first attitude, for example not pitched, of the apparatus
- gyration on the other side for example towards the right with respect to its direction of movement
- a second speed of the motor 8 corresponding to a second speed -V2 movement of the device in the rear direction and a second attitude, pitched, of the device.
- the general balancing of the device can be adapted to obtain each pitched or not up attitude desired, according to the different speeds corresponding. Changes of trajectory can be obtained according to the attitude of the aircraft, more or less upset or not, that is to say according to the inclination of the hollow body 1 about the axis 13 of the 7 axle motor relative to the immersed surface, for example (variant not shown) because the horizontal component (parallel to the immersed surface) of the forward hydraulic resistance is unbalanced and causes a gyration of a side of the device.
- the shell 11 may have flaps or ribs whose hydraulic effect is dependent on the tilting inclination of the device.
- these path changes can be obtained by a lateral shift of a guide member and / or brushing, or according to a spontaneous pivoting of a wheel following the change of direction of movement.
- changes of trajectory can be obtained by a given lateral inclination at each secondary outlet 50 with respect to the longitudinal direction orthogonal to the axle 7 and / or by different configurations of the members 5, 6. guide in contact with the immersed surface and / or by laterally offset braking members whether or not in contact with the immersed surface, according to the pitched attitude of the apparatus.
- the shell 11 has a portion 42 of wall extending forwardly from the opening 25, over its entire width, substantially marrying the contour of the front wheels 5.
- This portion 42 wall is provided with a pad 43 arranged so as to come into contact with the immersed surface to locally brake and / or take off the hollow body 1 if the apparatus takes a predetermined pitch attitude, the wheel 6 being peeled from said immersed surface.
- This pad 43 fixed, is arranged on one side, for example on the right as shown, secured to the portion 42 before the shell 11 and extends projecting radially outwardly from this portion 42 so as to come into contact with the immersed surface when the apparatus is in a pitched attitude, for a speed -V2 of displacement in the rear direction corresponding to the second speed, fast, rotation of the 8.
- the apparatus is swirled on one side (to the left relative to the direction of movement in the example shown) in the rear direction because of the friction of the pad 43 on the immersed surface and / or detachment of the wheel 5 front right.
- the shoe 43 is arranged in front of the axle 7, and comes, in the pitched attitude, in contact with the immersed surface at the rear of the drive axle relative to the direction of displacement (backward direction).
- the pad 43 is arranged to come into contact with the immersed surface only in said pitched attitude.
- the pad 43 in the normal unplugged attitude, the pad 43 is not in contact with the immersed surface, is remote from the latter, and is therefore inactive, all the wheels 5, 6 being in contact with the immersed surface.
- the control unit is extremely simple in its design and implementation. It is adapted so that the apparatus is mainly driven forward in a straight line.
- the motor 8 is interrupted from time to time and controlled in the reverse direction at the first slow speed (corresponding to the travel speed - VI) from time to time and at the second fast speed (corresponding to the travel speed -V2) of from time to time.
- the different control times of the motor 8: Tl in the forward direction at high speed + V, T2 in the backward direction at slow speed -VI, T3 in the reverse direction at normal high speed -V2, and T4 in the interruptions of the motor 8, are defined randomly (by a random generator, that is to say a pseudo-random variable generator) and / or in a predetermined manner.
- these durations can be defined so as to limit the entanglement of the cable 3, that is to say by ensuring that the accumulations of the periods of gyration on the left are similar to the accumulations of the times of gyration on the right.
- T1 is between 10s and 1 min, for example of the order of 20s; T2 and T3 are both less than T1, for example between 3s and 15s, in particular between 5s and 8s; and T4 is less than each of the durations T1, T2, and T3, is between 0.5s and 5s, in particular is of the order of 2s.
- each pitch attitude of the device does not require a particularly complex operating logic in that it can be obtained by simply balancing the device in production.
- the presence of the pad 43 facilitates this control, this pad 43 serving as an abutment limiting the pivoting in the pitched attitude.
- this control can remain relatively imprecise to the extent that the period of pitch up attitude of the device are low, this configuration of displacement does not correspond to the normal cleaning configuration.
- the apparatus according to the invention is extremely simple to design and manufacture, and therefore very economical, but nevertheless very powerful. Indeed, with a single electric motor 8 and a control unit reduced to its simplest expression, all the most complex functionalities of an electrical appliance are obtained.
